Title: Transistor and its manufacture
Inventor: TOYOOKA TETSUO
IPC: H01L29/732
Filed: 1984-02-28
Abstract: PURPOSE:To reduce the base resistance without deteriorating crystallization of a silicon by a method wherein an insulating film covering at least a part of an emitter region is extended to a base region encircling the emitter region with the width no exceeding 1mum. CONSTITUTION:An n type epitaxial layer 2 with low impurity concentration is grown up to the thickness of 1-20mum on an n type silicon substrate 1 to be a collection region with high impurity concentration. An oxide silicon film 10 is formed on the surface and then a part of the film 10 to be a base region is removed. A polycrystalline silicon film 11 is formed on overall surface and boron ion B<+> is implanted in the film 11 by ion implanting process. After removing the film 11 excluding its part on the base region forming part, a nitride silicon film 12 is formed on overall surface. A base region 5 is formed by means of diffusing boron impurity doped in the film 11 in the layer 2. The films 12 and 11 on an emitter forming part in the resist 5 are selectively removed to make an opening 13 for implanting arsenic ion As<+>. An emitter region 8 may be formed by means of diffusing the ion As<+> in the oxidizing atmosphere.

Inventor: TAKEDA JUN
IPC: F25D19/00
Filed: 1999-02-16
Abstract: PROBLEM TO BE SOLVED: To ensure stable cooling performance in a refrigerator in which a condenser is forcedly cooled with a cooling fan. SOLUTION: Upon passing through a demountable filter 11 provided frontally of a suction inlet 5 in a machine chamber 4 and having a plurality of vent holes cooling air by a forced ventilation action of a cooling fan, dust is caught by an internal periphery end surface of the vent holes. When the plurality of the vent holes are clogged with dust, the dust is removed by a hand of a user by removing the filter 11, and hence no dust is deposited on the condenser to ensure stable cooling performance without causing any heat dissipation problem.

The packing is composed of including of at least a water repellent oil absorption fibrous body. The water repellent oil absorptive fibrous body is formed by splitting or pulverizing, for example, natural timber to a fibrous form and subjecting the timber to a heat treatment in a specific temperature range, thereby forming the carbonaceous water repellent oil absorptive fibrous body which is partly carbonized in fiber texture. If such oil absorption structure 1 for cooking is used at the time of cooking, such as stewing, the coil component bleeding out of the meat is effectively absorbed.  The oil absorption structure 1 for cooking is capable of having the effect of the small lid resting directly on the material to be cooked during cooking in combination by the absorbed weight and is, therefore, capable of suppressing the breaking of boiled and seasoned food into pieces, etc.

Filed: 1985-03-01
Abstract: PURPOSE:To improve the operativity and rate of the recovery of a deteriorating developer with simple constitution by moving a developing device to a developer recovery position distant from a body to be developed and collecting it by utilizing the gravitation of the deteriorating developer. CONSTITUTION:A developing device 4M at the recovery position is in an orientation state where a developing device 4Y at a development position is rotated clockwise by 90 deg.. When a developer recovery command is generated, a scraper 11 is bright into contact with the sleeve of a developing roll 46 and a driving force necessary for recover is transmitted to only the developing device 4M to rotate screws 43 and 44 and the sleeve 46 of the developing roll 46. Consequently, the developer sticks on the developing sleeve 46b and is carried, but the carried developer is scraped forcibly by the scraper 11 pressed against the developing sleeve 46b and moves out of the restraint magnetic field of the developing sleeve 46b, so that the developer falls in a recovery tank 12. Thus, the deteriorating developer is recovered and replaced with a new developer.
